According to David Palmer's 2006 book, Parent's Guide to IQ Testing and Gifted Education, the average score for customary intelligence tests is 100 with a standard deviation of 15; approximately 50% of the population will score between 90 and 109 on a modern IQ test.
How long the decomposition of compostable plates takes is a question that many people might ask, and several factors influence what the answer is. Generally, if a compostable plate is placed in a commercial compost facility, it will take less than 180 days to completely decompose.
An unstructured pile can take up to two years, but in a bag or a 3 ft. x 3 ft. bin, you should see results within 6 - 10 months, depending on the weather and the types of leaves. If youâre impatient, you can shred the leaves before composting them. This will greatly speed the process.
